Fig. 6From: Self-Assembled Superparamagnetic Iron Oxide Nanoclusters for Universal Cell Labeling and MRIEffect of the SPIO nanoclusters on cell fate with Annexin V/PI staining FCS analysis. The SPIO nanoclusters (5 and 20 μg/ml) labeling for 24 h do not induce any significant apoptosis or necrosis compared to control in NIH3T3 (a, b), Raw264.7 (c, d), and HepG2 (e, f) cells using FCS assayBack to article page
